The Walk Bike Clackamas Plan is a comprehensive, long-term vision to improve opportunities for people who walk and bike in Clackamas County.

Adopted Walk Bike Plan  Adoption Materials

The plan, which applies to all urban and rural unincorporated areas of Clackamas County:

• Establishes infrastructure priorities, such as where to build new bike lanes and sidewalks, which will help the county apply for future grants and other funding opportunities
• Identifies programs that increase safety and convenience of walking and biking (like Safe Routes to School).
• Updates active transportation polices and adopt performance measures so we can track progress during implementation
• Serves as the pedestrian and bicycle transportation elements of the county’s updated Transportation System Plan (TSP)

Key Terms and Definitions

• Active transportation: human-powered modes of travel, including walking, rolling a wheelchair, and riding a bicycle.
• Facilities and infrastructure: designated places for people to walk, roll, and ride a bike, such as off-street shared-use trails, painted bike lanes on streets, marked and signalized crosswalks, and sidewalks and multiuse paths.
• Equity: reducing or eliminating disparities by thoughtfully spreading resources to overcome the unique barriers different groups face.
• Health equity: providing fair access to opportunities and resources for people to achieve physical and social health and well-being, and reducing barriers caused by circumstances outside of a person’s control, such as race, ethnicity, or social background.
• Communities of interest: groups of people who have experienced or continue to experience inequitable access to resources in society. Walk Bike Clackamas is focused on achieving equitable outcomes for the following communities of interest:
  • Black people, Indigenous people, and People of Color (BIPOC)
  • Immigrants
  • People with limited English proficiency
  • Low-income and low-wealth community members
  • Low- and moderate-income renters and homeowners
  • People with disabilities

The Molalla River (Knights Bridge Road) Bridge in the Canby area is an important connection for delivery of goods and services throughout the region. Bridge repairs will include painting, sealing cracks on the deck, resurfacing the deck, and repairing the concrete columns and bridge approaches. This project also includes seismic upgrades. 

Why

To preserve and extend the life of the bridge, to remove weight restrictions, allow for traffic to cross in an emergency, and to improve resiliency within our essential transportation network in the event of an earthquake.

Schedule

• Design: May 2022 to March 2023
• Right of way: April 2023 to Spring 2024
• Construction: May 2025 to November 2025

Traffic impacts

• A four-month full road closure will start June 16 to pave the deck and perform bridge repairs. The closure is scheduled through October 2025. When construction can occur with traffic, single-lane closures will guide travelers through the work zone.
• Enjoy extended weekday hours on the Canby Ferry through Sept. 12:
  We're extending the Canby Ferry hours of operation through Sept. 12 to help move traffic in the Canby area during several construction projects. Riders can cross the river between  6:30 a.m. and 8:30 p.m., Monday - Friday through Sept. 12. Check for regular updates at www.bit.ly/canbyferry or call the Canby Ferry Information Line at 503-650-3030.
   

Knights Bridge Park closure

For the public's safety, Knights Bridge Park will be closed for the duration of the construction on the western bank of the river. The protected area will allow for reclamation and restoration of the western riverbank and will be used as a staging area by the contractor.

Current activities

• Construction coordination with Farline Bridge, Inc.

Funding

• Project estimate $5.4 million
• Funding is provided from ODOT Local Bridge Program with a 10.3% match from county road funds 

In early 2021, heavy rains and strong winds caused fallen trees in Johnson Creek to damage the culvert supporting the road on Hideaway Court, in the Damascus and Boring areas. A temporary bridge is in use until the culvert can be replaced.

The culvert will be replaced with a bottomless culvert to allow for safe fish passage. 

Why

To preserve residential access.

Schedule

The county began the design phase in April 2021. Construction is planned between July and Aug. 2023, during daytime hours. Work will take up to 5 weeks to complete.

Traffic impacts

Single-lane closures will be needed during construction.

Current activities

Waiting for final design plans. Will send out construction bid by March 2023.  

Funding

• Project estimate $950,000
• Funding is provided from Damascus County Road Funds

In early 2021, heavy rains and strong winds toppled trees, causing the slope to collapse next to Rugg Road near the Hideaway Court intersection in the Damascus area. A retaining wall will be built at this location.

Temporary protective sheeting and plant seeding are in place until permanent repairs are constructed.

Why

To stabilize the slope next to Rugg Road.

Schedule

• Design: March 2021 - March 2022
• Construction: July 2024 - Oct. 2024

Traffic impacts

Building the retaining wall will require two temporary road closures. Rugg Road will close for 4 weeks to place the anchors and construct the wall facing. The road will then open to traffic for 3-4 weeks for the wall to settle properly. After this, the road will close for another 4 weeks to construct the final roadbed, add guardrail and pave the road.

Road closures are needed for the majority of construction. While the road closure schedule may need to be adjusted, the tentative plan is:  

• Road closed: July 8th to Aug. 11 
• Road open: Aug. 12 to Sept. 18 
• Road closed: Sept. 19 to Oct. 17

When a road closure is not necessary for construction, expect shoulder and lane closures with flaggers guiding vehicles daily through the work zone between 7 a.m. to 6 p.m., Monday through Friday. While we do not expect any weekend work, it may be needed depending on many factors. Local access to driveways will be maintained. Pedestrian access will be provided.
